Rlly need help with Linear equations in any form ;-;
S_A_V [24]

Answer:

y = -x - 2

Step-by-step explanation:

Find two points on the line

(0, -2)

(4, -6)

(Y2-Y1)/(X2-X1) = gradient of the line

Where (X1,Y1) = (0, -2) and (X2,Y2) = (4, -6)

(-6--2)/(4-0)

(-6+2)/4

(-4)/(4)

-1

Y = (-1)X + c

Substitute either set of coordinates in to find c.

(0, -2)

Y = (-1)X + c

-2 = (-1)0 + c

-2 = 0 + c

-2 = c

(4,-6)

Y = (-1)X + c

-6 = (-1)4 + c

-6 = -4 +c

-6 + 4 = c

-2 = c

Y = -X -2

An aquarium measures 61 cm long, 30.5 cm wide, and 30.5 cm high.If the tank is only filled to 80% capacity with water, how much
LiRa [457]

Answer:

V=45396.2\ cm^3

Step-by-step explanation:

Given that,

The dimensions of an aquarium are 61 cm long, 30.5 cm wide, and 30.5 cm high.

The tank is filled to 80% capacity with water.

We need to find the water needed for this tank.

The volume of cuboid is given by :

V=lbh

As it is filled to 80% capacity, so,

V=\dfrac{80}{100}\times lbh\\\\=0.8\times 61\times 30.5\times 30.5\\\\V=45396.2\ cm^3

So, 45396.2\ cm^3 of water is needed for this tank.
